Being more specific, my question is:
That switch should turn on the additional blower as soon as it is changed from zero to speed 1, 2 or 3?
Or its ignition will depend on the temperature (thermostat)?
I ask the question, I know sounds silly, but what happens is that I have never turned on the heating system and I have many doubts with it, especially with the automatic heating control that comes in my car.
When I move the swtch from position zero to 1/2/3, nothing turns on, and what I want to know if, to do the test, I must put the automatic heating control knob (between the seats) in position DEF (max. heat and not thermostatically controlled), assuming that if the blowers do not turn on, then I should check the fuses, relays, etc ...
Thank you!
